She has been living in France since leaving the house. She has two kids from different marriages, and they’ve been scraping by. Now she is trying to get back to London to see the baby. The baby, Libby, is the final perspective. She was born just about a year before everything came to an end in the house. She is now twenty five, and has inherited the huge house along the Thames.
